WebFactoring polynomials helps us determine the zeros or solutions of a function. However, factoring a 3rd-degree polynomial can become more tedious. In some cases, we can use grouping to simplify the factoring process. ... Factor 3rd degree polynomials by grouping. WebSolution. Always go back to the fact that the zeros of functions are the values of x when the function’s value is zero. We can see that when x = -1, y = 0 and when x = 1, y = 0 as well. Hence, the zeros of f (x) are -1 and 1. Example 2. The graph of f (x) is shown below. WebFactoring Calculator. Enter the expression you want to factor in the editor.
